SAP HANA stores the necessary data in RAM (main memory) rather than on a hard disk. By using the main memory SAP HANA, a combination of hardware and software processes massive amount of real-time data.

The pivotal functionality of SAP HANA is real-time analytics besides deploying and developing real-time applications.

The SAP HANA database is developed using C++ and at present, the operating system supported by SAP HANA is SUSE Linux Enterprise Server x86-64 (SLES) 11 SP.

Though SAP HANA is particularly optimized for column-based approach, it also supports row-based approach.

The activities such as data-intensive operations, additional complex calculations and functions will be managed by in-memory storage of SAP HANA database. Therefore, there is no need for materialized aggregates. In fact, it has some benefits such as simplified application logic, simplified data model and a higher level of concurrency.

SAP HANA is fast because of the following factors,

• In-memory
• Row and Column database
• Massively parallel processing
• Calculation Engine

Here are the components of SAP HANA database architecture,

• Index server
• Persistence layer
• Preprocessor server
• Name server
• Statistic server
• Session and Transaction manager
• XS Engine

Types of modeling views

• Analytic view
• Calculation view
• Attribute view

The three major types of engines in HANA are,

OLAP engine (used of analytic views)

Join engine (used for attribute views)

Calculation engine (used for calculation views)

There are two types of packages in HANA such as Structural package and Non-structural package.

Structural package has sub-packages but not repository objects whereas Non-structural package contains both sub-packages and repository objects.

The three types of Schemas in HANA are,

• SLT derived schema
• User-defined schema
